Poisson结构与广义Kahler结构

Poisson structures and generalized Kahler structures

Ryushi Goto

摘要:

设X是具有非平凡全纯Poisson结构的紧致Kahler流形。然后X上存在具有一个纯旋量的非平凡广义Kahler结构的形变。我们证明了X的每个Poisson子流形都是关于变形的广义Kahler结构的广义Kahler子流形,并提供了广义Kahler子流形作为全纯Poisson子流形产生的非平凡例子。我们还获得了由泊松结构构造的双厄米结构的无障碍变形。

英文摘要:

Let X be a compact Kahler manifold with a non-trivial holomorphic Poisson structure. Then there exist deformations of non-trivial generalized Kahler structures with one pure spinor on X. We prove that every Poisson submanifold of X is a generalized Kahler submanifold with respect to the deformed generalized Kahler structures and provide non-trivial examples of generalized Kahler submanifolds arising as holomorphic Poisson submanifolds. We also obtain unobstructed deformations of bi-Hermitian structures constructed from Poisson structures.
